[Qemu-devel] [Bug 1708551] Re: macOS Guest Reading USB 3.0 Bus as USB 2.0

[Thomas Huth]

Ok, could you maybe try something like this instead:

 qemu-system-x86_64 ... -usb \
    -device qemu-xhci,id=xhci \
    -device usb-tablet,bus=usb-bus.0 \
    -device usb-kbd,bus=usb-bus.0 \
    -device usb-host,bus=xhci.0,vendorid=0x05ac,productid=0x12a8

i.e. use "bus=xhci.0" for the usb-host device?

Title:
  macOS Guest Reading USB 3.0 Bus as USB 2.0

Status in QEMU:
  Incomplete

Bug description:
  Description:
  I'm having trouble with USB Passthrough. Running `system_profiler 
SPUSBDataType` on macOS guest confirms that the system "sees" my device, and 
that qemu is passing *something* through. However, the system sees my 
connection as USB 2.0, even though i'm passing through XHCI controllers 
(nec-usb-xhci/qemu-xhci). I suspect this is the reason why my guest is unable 
to recognize my iPhone in XCode & iTunes.

  Parameters:
  QEMU release version: 2.10.0-rc0
  Bios: [patched version of OVMF](https://github.com/gsomlo/edk2/tree/macboot)]
  Command Line: https://pastebin.com/pBSYbrW1
  Host: Arch Linux
  Guest: macOS v10.12.6
  Guest System Info: https://pastebin.com/U1Tihxei

  Notes:
  1. Observed sometime after late-May-early-June of this year.

  2. Due to [a defect in qemu v2.8 which affected GTK
  users](https://bugs.launchpad.net/qemu/+bug/1578192), and [a recent
  change to macOS' booting process conflicting with qemu
  v2.9](https://lists.nongnu.org/archive/html/qemu-
  devel/2017-03/msg06366.html), i'm forced to use qemu v2.10.0-rc0 (as
  -rc1 fails to load OVMF right now).
